- Early repayments, late fees, insurance and lender-specific rounding are excluded.
How it works
The maths behind the repayment.
The calculator uses the standard amortisation formula every lender uses for principal and interest loans: the balance earns interest at your rate while each repayment knocks off a slice of principal, sized so the loan lands on exactly zero at the end of the term.
A longer term usually lowers the regular repayment but increases the total interest. Adjust the amount, rate, term and fees above to compare that tradeoff using figures relevant to you.
The rate you enter is the biggest unknown, your real rate depends on your profile, the asset and the lender. One application compared across our panel of 80+ lenders is how you find the sharpest one you actually qualify for.
